.The main object Ofelia invention is to I A provide a sender .of the type which di rec-- q-tively controls the operation of the semening devices 2o 5 with a; certain numericaldesigniition, than;

i-quenciesi 0 1 .Another ob ect 1s 'to provide a-sender'erlay impulses ofqvnrying ireranged to send out impulses in acc'bf'dzifice which the interval .'Of time required for transmitting impulses to designate one nn- -i f meral or character is the same as the time, 1- required for sending impulses to designate any-other numeral or chin-deter.

In order to attain the abovedefined ohjects, according to the principal feature of this invention, the impulse trimsmittin de'-. v ice is provided withn plurality of vi me, ingmembers forsending impulses of very- -in frequencies.
